Business Operations Platform
Built a Retool-based internal operations platform for managing people records, tech assignments, subscription billing, onboarding workflows, and external user provisioning. The platform allowed admins to assign tools directly or through tech packages, view package and tool details, manage billing records, trigger payment update flows, and search or paginate operational data across users, assignments, payers, and Google group configurations.
I designed the PostgreSQL schema and SQL queries for tools, packages, assignments, people, billing, and payment records, including nested response objects for cleaner front-end usage in Retool. I also implemented database functions and triggers to keep assignment costs in sync when tool or package pricing changed.
The project included integrations with Authorize.Net for subscription payment management, Dialpad for user provisioning and number assignment, Salesforce for onboarding records, Slack and n8n for workflow notifications, and Google Groups for access configuration. The system improved admin visibility, reduced manual lookup work, and created a more structured workflow for managing user tech subscriptions and onboarding operations.
